To all whom it may concern:

Be it known that I, AMBRosE Lnn'ra'rmaresiding at Test -Hoboken,:.

citizen of Italy, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Collar-Buttons,

ing, forming a part of the same. I

The object of the invention is to provide a collar button which can be easily'inserted in the buttonholes ofthe shirt band and collar and which will even permit the button-.

- ing of the collar with one hand, which will hold the collar securely, will permit very easy unbuttoning, and, will not injure the buttonholes. I

These and other objects are provided for in the structures shown in the accompanying which are representative embodidrawing, ments of my invention. After considering these, it will be apparent that other modifif' cations may be made within the principles of the invention, and I do not limit myself to details except as claimed.

Figure 1 is a side elevation showing a (301- lar button embodying my invention inserted in the neck band of a shirt and in one buttonhole of a collar, andpa'rtly inserted in' the other collar buttonhole.

Fig. 2 is a front elevation of the button in place in a fully buttoned collar.

Fig. 3 is a top plan view, the base, however, being shown in section. 4

Fig. 1 is a side view of another form of the invention. Fig. 5 is a top View. Fig. 6 is a front end view of the same. The form of the invention shown inFigs. 1, 2 and 3 comprises a shank 1, head 2 and base 3. All these parts may be of metal and formed integral, or they may be of other suitable material, or formed separately, and suitably connected together. In the particular example shown, are of metal and may preferably be integral. The base 3 is of bone, shell, or other desired metal, connected to the shank.- The connection is made in the present example by providing the shank with a stem 4 extending beyond shoulders 5 formed on the shank. The stem 4: passes through a hole in the center of the base. and is thereafter pressed or hammered to form an HPSBtPOItlOIl or flange 6 at the back of the base, which holds the base firmly in position against the shoulg fully. described and represented in thefollowing specification and the accompanying draw- V 1 head to the points wherethe'shoulders 5 are formed. The vertical thickness of the shank is maintained the same throughout,as shownthe shank .1 and head 2 ders Thefiange'G preferably is accom-.

modated in a recess 7, in the back of the base.

Preferably, the shank is relatively wide in a horizontal direction compared to its vertlcal thickness.

This isv conveniently pro{ vided for in the present embodiment by..

making the sides 1 of the shank divergent from the point'where theshank joins the in Fig. 1, and this dimension. is less than the width-of the shank for'at least a considerable part of its length, asflshown in Fig. 3.

- The head 'is preferably of: approximately triangular form as viewed from thefront.

its upper edge 8 ispreferably substantially flush with the upper surface 90f the shank, as indicat'edinFigs. 1'and2. Close to the shank at each side of it thehead hasa portion 110, or shoulder, extending laterally a considerable distance: from the shank. The lower. end of the head is formed into av rounded point 11. The baok of this point is preferably beveled away at 12,"Fig. so as to.sharpen the point for easier insertion into the buttonholes, as will appear.

At the placewherethe upper surface of the shankand' the front surface of the headintersect, the material is formed so that this intersection is a curve 18 of smallradius. The beveled point 11 of the'head is easily inserted in the neck band buttonholes of a shirt and is shown .ininserted positionin Fig. 1 with the shank '1 extendingth'roughfastened. Fig. 1 shows how the lower edge e of the button hole may be hooked under the beveled] point 11 of the head,'and this may be done if necessary or desirable by using only one hand. By simply pulling up on the collar, the head of the button will slip through the buttonhole until the upper ed 'e of the buttonhole passes the rounded suFface 13 at the top of the head, and then the buttonhole will slide back and naturally locate itself behind the head in the position shown in dotted lines in Fig. 1, and is then held securely from accidental displacement by the side flanges or extensions 10,

and by the lower overlapping portion of the ihead. To remove the collar, it is only necessary to pull the upper part of it slightly so that the upper edge f of the buttonhole slides forward of the head at the top, and

then further downward-pressure will immediately unhook the buttonhole from the head. The operations of buttoning and unbuttoning the collar may be performed with great rapidity and ease. -The collar buttonholes slip on and off of the button so easily thatthere is no reasonable chance of injuring the buttonholes.

7 Figs. 4;, 5 and6 show a somewhat modified formof theiinvention in which the base .15 may be, of'metal and the head 16 may be substantially round. The entering edge 17 of the head may also be rounded and not beveled, although the head adjacent to this edge may be somewhat'reduced in thickness, as indicated in Fig. 4. The shank 18 in this embodiment is formedv with apart 19 adjacent to the headwhich is even wider tha'n'the-shank of Figs. 1 to to give greater security against turning of the but ton; This wide portion, defined by the parallel sides 20, extends considerably out-.

wardly from thebase to a point 21, where the width of the shank is reduced to the point 22, where the shank connects with the.

head. The'sides 23 of the head, extending laterally considerablybeyond the side edges of the shank, securely retain the collar after it is buttoned. device in buttoning and unbuttoning the 1 collar is substantially the same as explained in connection invention.

What is claimed is: 1. A collar button, comprising a base, a

with the other form of the shank, and a head connected at one of its sides to the outer end of the shank, the shank being narrow in a direction parallel to the vertical dimension of the head and l The manipulation of this relatively much wider horizontally for at least part of its length.

2. A collar button, comprising a base, a;

head, and a shank, the head being approximatelyfiat and thin in relation to its facearea, and being connected to the shank at one of its edges so that the head extends at substantiallyia right angle from one side of one of its edgesso that the head extends at 5 substantially a right angle from only one side of the shank, theshank being thin in a direction parallel to the direction in which the head extends from it and relatively widernearthe base in a directiontransverse that first mentioned, the shank being narrower in the same directionnear the head. 4. A collar button,comprising a base, a head, and a shank, the head being approximately flat and thin in relation to its face area, and being connected totheoshank at one of its edges so that the head extends at substantially a right angle from only one side of the shank, side portions of the head extending'considerably laterally from the adjacent edges of tl1E Sl1tI1l ,',tl18 shank being thin in a direction parallel to the direction in which the head-extends from it and relatively wider near the base in a direction transverse that first mentioned.
